I just purchased the Samsung PX2370 LED samsung monitor. I took about an hour to get the colors and gama the way I like it. I have been told it's best to keep with a monitors static resolution (in this case 1000:1) The Dynamic Contrast Ratio is (5 million: 1 but that is a marketing number) On this montior the dynamic contrast ratio really looks better.

Does Dynamic contrast have any disadvantages?

Dynamic Contrast basically blows out white detail and destroys black detail. When Dynamic Contrast is enable, you will theoretically get a better Contrast Ratio (i.e. measuring a pure black square against a pure white square). However, you'll be losing detail in the high intensity and white areas of the image, as well as in the dark areas of the image (aka black crush). The best way to illustrate it is to view some test patterns with Dynamic Contrast on, and then with it off. The best test image site is probably this: http://www.lagom.nl/lcd-test/ Also, get a grayscale up on your monitor and notice the effect Dynamic Contrast has. Here is a good 0-256 grayscale: http://i.pbase.com/o6/78/287278/1/75285378.fButmPlS.GreyscaleStep8.JPG Dynamic Contrast is artificial and will most likely clip information in the image at some point, not allowing you to see all of the intended image. However, if you like the way it looks (for example, if you think it looks cool with games), then by all means do what looks best to you. But as far as accuracy goes, Dynamic Contrast is best left off.

Also, turning off features like dynamic contrast, noise canceling, dynamic color, etc. can help to cut down on lag. Some tv's game modes speed up the image by simply switching off all those features.

Leave it off. Also go and grab yourself a calibration disc. At the very least use the THX optimizaton mode found on many DVD's and Blu-Ray's to dial in your settings. All the dynamic stuff and fancy processing may look "ultra sharp and hyper realistic" at a casual glance, but also look ultra fake, noisy, and have poor blacks when you look at it more critically.

I did end up turning off dynamic. Thanks for the heads up.


The one feature that works wonders is Samsungs MagicColor feature. NO matter how much I filled with the colors I could never get them like I wanted them. Turning on that magiccolor feature and it hit the right tone exactly,.

Your console is already taking care of your HDMI black levels contrast etc. (Xbox 360 Expanded) (PS3 On Full On Automatic)

for the video settings

I find in my case Dynamic Contrast does not sync correctly and masks textures

leading to darker the normal areas and shadowing

Even though the default TV setting under Game Mode recommends Medium in the long run I'd set it to off

for cleaner smoother textures/lighting

However the down side being realistic looking daytime and nighttime does take a hit with Dynamic Contrast being set to off

I just bought a del s2330mx and set my monitor to the settings on this site :http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/48942-dell-s2330mx-23-led-monitor-review-9.html

- used custom color mode
- ensured dynamic contrast was off
- lowered the brightness to 35 (which resulted in a 124 cd/m2)
- lowered Red to 86
- lowered Green to 78
- lowered Blue to 82
- Slightly adjusted windows gamma setting to correct for gamma
- All other settings left to default levels

how do I close dynamic contrast ratio, how do i adjust the gamme to 2.20

thanks...
